HORSESHOE.

SPECIFICATION forming part of Letters Patent No. 834,200, dated January 12, 1886.

Application filed October 22, 1885. Serial No. 180,650.

To all whom it may concern.- 1

Be it known that I, GEORGE G. SCHROEDER, a citizen of the United States, residing at Washington, in the District of Columbia, have invented a new and useful Improvement in Farriery, of which the following is a specifi cation.

My invention relates to farriery, and is an improvement on the class of supplementary detachable horseshoes supplied with removable calks adapted to be adjusted to any ordinary horseshoe.

My improvement has special reference to the method and means for connecting the supplementary shoe.

Another part of my invention relates to a device whereby my sub-shoe can be applied" over a shoe that has a fixed toe-calk.

To the accomplishment of my purpose my invention comprises certain peculiar arrangement of the toe and heel flanges, and, further, the provision of novel and peculiar clamps that are turned in position within apertures provided for their reception, and are thereby held, when adjusted, by means of screwthreaded nuts, and in combinations of the several devices, all as hereinafter fully set forth, illustrated in the drawings, and specifically pointed out in the claims.

Referring to the accompanying drawings, in which like letters of reference point out similar parts on each figure, Figure 1 is a perspective view of a shod hoof having attached thereto an ordinary shoe, and also a supplementary shoe embodying my invention. Fig. 2 is a sectional view thereof. Fig. 3 is an under plan view of the supplementary shoe illustrated in Fig. 1, showing quadrangular apertures for reception of detachable tapering calks, also showing ears apertured for reception of fastening-clamps, one of such clamps being shown in place screwed home by its fastening-nut, one shown in place without its fastening-nut, and one ear being shown without any such clamp. Figs. 4 and 5 are detail views of the clamp and fastening-nut. Fig. 6 is a perspective view of a part of the shoe illustrated in Fig. 3, the opposite side being shown. Fig. 7 is a sectional view thereof. Fig. 8 represents a tool for adjusting the clamps and their screw-nuts. Fig. 9 represents a modified form of removable calk.

(N0 model.)

beveled sides inclining from the top face of' the shoe B, adapted to receive quadrangular tapering calks C, although said calks can be triangular in cross-section or have polygonal sides and be within the scope of my invention.

Fig. 9 illustrates a calk triangular in cross sectiomas one form of modification, and it will be readily understood that apertures 12 must be made to conform to whatever may be the shape of the calk employed.

D is a packing of rubber, leather, or any suitable material, preferably placed between the two shoes, that will keep the calks from rattling should the shoe A be uneven at any portion of its lower faceplane.

B are inwardly-projecting ears orificed at o for a purpose hereinafter set forth. Below said orifices,and upon the under surface of the shoe B, each ear B is countersunk, the peripheral circumference of such countersinks' (see If) being greater than that of the orifices b for a purpose that will be explained hereinafter.

E represents clamps, having a shank, e, screw-threaded at e, and having a countersink, e' for the operating-blade of a screwdriver or appropriate tool. Said clamp has an extending foot-plate having its surface serrated or roughened to make it take firmly onto and grip the surface upon which it is brought to bear. preferred form of such clamp-plate 6 the inner edge of which should be in about a right line, as shown at 6 This prevents it from liability to swing round when in the position shown at the toe end of the device, Fig. 2.

F is a shouldered nut, having a central screw threaded aperture, forming a female screw for the male screw-thread e on the shank e of clamp E. It will be observed (see Figs. 2 and 5) that said nut has two diameters, the smaller area adapted to loosely fit within an orifice, b", the larger one within the countersink b.

It will be seen by the drawings that the sub- Fig. 4 shows in detail the shoe B has a cut-away part, B at the toe I thereof, the object of which is to admit the periods, frequently renewed during a season.

passage of the fixed toe-calk frequently employed on ordinary shoes.

In all forms of the shoe B this location of the toe and heel flanges is preferred, for the following among other reasons: Such flanges upon the inner are are not as liable to be broken or worn away by striking an opposite shoe or by an animal kicking against any obstruction. Especially is this construction advantageous for fittinga shoe B onto variouslyshaped and diversesized shoes A, as the heelbars or radii m m of the arc of the shoe can be bent inwardly or spread outwardly (see arrows and dotted lines, Fig. 3) to accommodate the subshoe to the surface area of an underlying shoe, and the flanges b will then take directly against the inner flat surface edge of the crown or central point of the shoe A, thus preventing lateral displacement, whilea toe-flange, b, will impinge against the inner arc of the n 1r derlying shoe.

In carrying into practice my invention a shoe B is first supplied with calks O, placed within the receptacles provided therefor, a packing, D, is preferably placed upon the upper surface of the shoe, covering the fiat heads of the calks O,and the shoe placed flat against and below the shoe A. The stems of the clamps E are then placed Within orifices b and are then turned half-round until they are in the position plainly illustrated at the toe end of Fig. 2. A nut, F, is then dropped into each countersink b and over the stem of each clamp E. Said nuts are then turned until their screw-th read takes onto the screw-headed shank e, and continuously turned until all slack is taken up and the two shoes are firmly clamped together, as will be readily understood by this description and by reference to Figs. 1 and 2 in connection therewith.

In Fig. 8 I illustrate a tool that may conveniently be used in carrying out my invention. Its adaptation for the purpose intended will be manifest.

From the foregoing description it will be seen that I provide a practical, inexpensive, sub-shoe, known asa creeper, for animals, that can be quickly adjusted by any person, however inexperienced in farriery, and that will be appreciated by all who have occasion to use such an appliance;

By employment of my invention, the tedious and expensive process of roughening horses can be entirely dispensed with.

In many localities frosts and ice-clad roads come on suddenly, and often last for brief In such cases it is not desirable to have an animal continuously and permanently roughshod, and thus affect his gait and draft properties; but I provide by'my invention a subshoe that can be put on and offby an ordinary person having charge of a stable.

Besides the benefit of my sub-shoe for iceeovered roads, it is equally serviceable for otherpurposessuch as cavalry and ordnance traversing rough ormountainous surfaces-as it is obvious that the tractile powers of the draft-animal are materially assisted by the purchase secured by means of the calks 0.

Having now fully described my invention,

what I claim, and desire to secure by Letters Patent, is-

1. A supplementary horseshoe having inwardly-projecting ears B, provided with apertures b and countersinks b, surrounding a said apertures, in combination with clamps E and shoulder-nuts F, as and for the purpose intended, substantially as described.

2. In asnpplementary horseshoe, the clamping devices E, having a shank, e, screwthreaded at e, and provided with countersink 6 and having a laterally-extending plate, 6 with roughened surface, in combination with shouldered fastening-nut F, having a central screw-threaded aperture, as and for the purpose intended, substantially as described.

3. A supplementary horseshoe or creeper, B, having toe and heel flanges b 12, extending upward and located within the inner are of the shoe, as and for the purposeintended, substantially as described.

4. A supplementary horseshoe having a cut-away portion, 13*, at the toe portion, as and for the purpose intended, substantially as described.

5. The combination of an ordinary horse- GEORGE G. SOHROEDER.
